Abstract

Background: Dental caries is a multifactorial disease that causes reversible decalcification and cavitation of susceptible teeth exposed to sugary substrates over a period of time in the oral cavity. It gives clinical and social burdens to the child patients and their parents/carers. Stainless steel crown (SSC) restoration is one of the restorative treatment options in the management of carious primary molars. Aims: The Hall technique is a biologic method of managing primary teeth by sealing in the caries with preformed metal crowns (SSCs). The objectives of this study were to assess and compare the primary and secondary treatment outcomes of stainless steel crown restorations using the conventional method and the Hall technique in primary molars immediately after placement and over a 12-month period using both clinical and radiological parameters. Methods: The study was a randomized control clinical trial using a split mouth approach. A total of 25 stainless steel crown restorations using the conventional method and 25 stainless steel crown restorations using the Hall technique were placed in 25 subjects aged 3–8 years with a pair or pairs of unrestored enamel or dentinal carious primary molars matched for tooth type, dental arch, and extent of caries. All subjects were monitored and reviewed every 3 months for 12 months. Results: Twenty three subjects returned for follow-up. There was no statistically significant difference ( P -value > 0.05) between the conventional SSC restoration and the Hall technique for both the primary outcomes/major failures (irreversible pulpitis, dental abscess, peri-radicular radiolucency, and crown loss with tooth unrestorable) and secondary outcomes/minor failures (crown loss and tooth restorable, crown perforation, secondary/marginal caries, and reversible pulpitis). But, there was a statistical significant difference in the average time taken for the placement of the restorations between the two groups ( P -value 0.001). Conclusion: Both the conventional SSC restorations and the Hall technique can be provided for all the subjects in this study. The Hall Technique compared favorably well with the conventional SSC restoration in clinical and radiological outcomes. The Hall Technique appears to offer an effective treatment option for managing dental caries in primary molar teeth especially in a resource challenged environment where electricity and treatment under general aaesthesia can sometimes be a problem.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
